How to Use Batch Specific UoM in SAP for Accurate Inventory

In many industries such as pharmaceuticals, food & beverage, and chemicals, it is common for the same material to vary slightly in weight or volume between batches due to manufacturing or environmental conditions. Traditional inventory management methods, which assume uniform units of measure across all batches, fall short in such scenarios. SAP addresses this challenge with the Batch Specific Unit of Measure (UoM) functionality.

Batch Specific UoM allows users to maintain batch-dependent conversion factors between different units of measure (such as between Rolls and Metre), making inventory more accurate and business operations more transparent. This feature is particularly useful when dealing with variable-weight items or when regulatory compliance requires batch-specific tracking.

Business Scenario:

A garment manufacturing company procures fabric rolls from different suppliers. Although the ordering unit is “Rolls”, each roll can differ in usable area (in m²) depending on fabric thickness, stretching, or cutting tolerance. The actual area of fabric available per roll is batch-specific and must be tracked for accurate inventory and production planning.

Problem without Batch Specific UoM:

If every roll is assumed to contain a fixed m², it leads to inaccurate raw material planning, over- or under-consumption in BOMs, and errors in stock valuation or costing. This becomes a significant issue when each roll is priced based on the usable area.

Solution with Batch Specific UoM:

By enabling Batch Specific UoM in SAP, the company can maintain the actual square meters per roll as a batch-specific conversion. During Goods Receipt, the user records the true m² of fabric in each roll, allowing the system to reflect the correct inventory in both Rolls and m². This ensures precise material consumption, correct stock values, and better production efficiency.

In the following sections of this blog, we will walk through:

  • Configuration of Batch Specific UoM via IMG paths

  • Creation of characteristics and class to store batch-specific values
  • Material master setup with proportional UoM
  • Recording batch-specific quantities during purchase and Goods Receipt
  • Viewing inventory in both base and alternative UoMs

This functionality helps businesses gain better control over variable-material inventories and supports compliance with industry-specific textile and clothing production standards.

Step 1: Create Unit Measure (Transaction: CUNI)

Step 2: Activate Batch Specific UoM

Path: IMG --> Logistics -General --> Batch management -->Batch specific material unit of measurement -->activate batch specific material unit of measure

Step 7: Create Material/Product Master data (Transaction: MM01 or App: Manage Product Master Data)

You can create a material master record using MM01 or using Manage Product master data
